UNITED STATES PATENT OEEIOE.

JOHN GILMORE, JR., AND AARON WIOKS GILMORE, OF UTIOA, PA.

IMPROVED MODE OF SINKING WELL-TUBES.

Specification forming part of Letters Patent No. 58,809, dated October16, 1866.

Zo all whom it may concern:

Be it known that we, JOHN GILMORE, Jr., and AARON WIOKs GILMORE, ofUtica, Venango county, Pennsylvania, have invented a new and ImprovedMachine for Sinking'Water-"Wells, and we do hereby .declare that thefollowing is a full and exact description of the same, reference beinghad tothe aecompanyin g drawings and the letters of reference markedthereon. Y

Figure l represents our machine with all its parts adjusted in order. DD is a tube ot' iron- 1'. e., the well and pump tube. B is a drill; A A,the drill-rod, which is screwed together in sections, onejoint beingshown at s.

Fig. 3 is an end view of the drill-rod, showing a collar thereon withfour flanges, 4 5 (i 7. (Also, see 4 5 6, Figs. 2 and 1.) E is a collaron the inside of the tube D D, fastened tothe tube. l 2 3 are notches orgrooves in the collar, made so that when the drillrod A is forced down,the lianges 7 6 5 4 will fit into the notches l, 2, 3, and 3', (see Fig.4 and end view of the collar,) and thus prevent the lower or drillsection ot' the rod from turning, so that the saine can be unscrewed ats, thereby permitting the removal of the rod A While the drill-sectionmust remain in the well. O is a shoulder on tlle'upper end of the drill,which tits closeljr into the lower end of the well-tube D Dthereb vpreventing dirt from entering the tube while the saine is being driveninto the earth.

Our machine operates as follows, to wit: The drill is drawn up in theposition shown in Fig. 2. The tube D D is now driven down until it strikes a rock or hard clay, when it can be driven no farther. The tube D Dis then drawn back to the position shown in Fig. l, the drill remainingdown on the rock or clay. The drill can now be moved up and down betweenlthe end of the tube D D and the rock or clay, thus drilling a hole,when the tube D D can be forced after. When the tube is forced down therequired depth for water it is then drawn back until the collar Eclutches or meets the iianges 4 5 6 7. This opens the end oi' the tube DD, (as the drill-rod is smaller than the inside of the tube D D,) andthe drill-rod is then unscrewed ats and the rod withdrawn. This leavesthe lower end of the tube D D Open for water to enter, which is drawn upby a pump.

fhat we claim as our invention, and desire to-secure by Letters Patent,is-

The drill B, with the flanges 4 5 6 7, in conib'ination with the collarE and the tube D D, when the saine are constructed as described in theaforesaid combination, for the purposes set forth.
